I have recently made a ubuntu liveusb without persistency. it was fast, i liked it more than windows, so i wanted some persistency, although when i created a second liveusb this one with persistent memory it was very slow, everything was as slow as it was a windows installation used and uncleaned for 5 years. it was very slow. Preceeding questions. I cannot install it to my hard drive. it must be on that very pendrive. Why is it slow? How to make it fast again? Maybe i should use other distro, if yes, then wich one?
